Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-Figure 4 A steel washer production mold includes a support device for supporting stamping and collecting waste, and a pressing device installed on the top of the support device for pressing down and pushing the washer and pushing the material. Below the pressing device is an upper lifting device for supporting the stamping and separating the waste.

[0026] In this embodiment: the support device includes a support platform 101, a collection box 102 is provided below the support platform 101, a support frame 103 is provided on the support platform 101, and a hydraulic cylinder 104 is installed on the top of the support frame 103. In use, the plate is placed on the upper lifting device under the support of the support platform 101, and the hydraulic cylinder 104 supported by the support frame 103 extends to drive the lower pressing device to press down for stamping. The waste material generated by stamping falls into the collection box 102 for collection.

[0027] In this embodiment: the pressing device includes an upper mold base 201, a mold cavity 202 is opened under the upper mold base 201, an upper punch 203 is arranged at the center of the mold cavity 202, and a pusher assembly is arranged outside the upper punch 203. The pusher assembly includes a push plate 204, a pressure plate 206 is arranged above the push plate 204, and four push rods 205 are evenly arranged between the push plate 204 and the pressure plate 206. The push plate 204 is circular in shape and is slidably connected to the mold cavity 202. When the mold is opened, the washer is stuck in the mold cavity 202 and rises with the upper mold base 201. When the upper mold base 201 moves to the top, the pressure plate 206 will be squeezed by the support frame 103. The push rods 205 drive the push plate 204 to push the washer downward out of the mold cavity 202.

[0028] In this embodiment: the upper ejector device includes a lower mold base 301, a support assembly is provided above the lower mold base 301, a lower punch 305 is provided at the center of the support assembly, and a blanking hole 306 is provided at the center of the lower punch 305. The support assembly includes a support plate 302, and four limiting rods 303 are evenly arranged below the support plate 302. Springs 304 are installed on the outside of the limiting rods 303. The support plate 302 is slidably connected to the lower punch 305, and the limiting rods 303 are slidably connected to the lower mold base 301. Under the support of the lower mold base 301, the lower punch 305 cooperates with the mold cavity 202 to stamp the overall contour of the washer. The upper punch 203 cooperates with the blanking hole 306 to stamp the inner hole of the washer. During the stamping process, the scrap follows the support plate 302 down the limiting rods 303 and presses down the springs 304 to make way.

[0029] Working principle: During use, the sheet metal is placed on the support plate 302 under the support of the support table 101. Then, the support frame 103 supports the extension of the hydraulic cylinder 104, which drives the upper mold base 201 to press down. This causes the lower punch 305, supported by the lower mold base 301, to work with the mold cavity 202 to stamp the overall contour of the washer and lift the push plate 204. At the same time, the upper punch 203, in conjunction with the blanking hole 306, punches the inner hole of the washer, and the stamped waste material falls into the collection box 102 through the blanking hole 306. The remaining waste material follows the support plate 302 down along the limit rod 303. The spring 304 is compressed to allow for clearance; after stamping, the hydraulic cylinder 104 is shortened, causing the upper mold base 201 to move downward to open the mold. During this process, the scrap is pushed up by the spring 304 along with the support plate 302, while the washer is stuck in the mold cavity 202 and rises with the upper mold base 201, realizing the separation of the washer and the scrap. At this time, the scrap is removed first. When the upper mold base 201 moves to the top, the pressure plate 206 is squeezed by the support frame 103, which will drive the push plate 204 through the push rod 205 to push the washer downward out of the mold cavity 202. At this time, the washer is collected.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
